  • This invention pertains to graft copolymers and, more particularly, to compounds having N-methylol derivatives of acrylamide grafted onto poly(oxyalkylene) polymers to form graft copolymers which are crosslinkable and to methods for preparing such graft copolymers.
  • Poly(oxyalkylene) compounds including poly-(oxyethylenes), poly(oxypropylenes) and copolymers thereof have many and diverse industrial uses such as treatments for metals, paper, textiles and the like.
  • the poly(oxyalkylene) compounds are readily removed from the surface of the substrate materials during the various treatments employed and its effectiveness is, thus, reduced.
  • modified poly(oxyalkylene) compounds which possess many or all of the properties of the unmodified compounds plus new or improved physical and/or chemical properties such as, for example, providing a more durable coating.
  • a process for preparing graft copolymers of poly(oxyalkylene) compounds with a wide variety of olefins which is reported to substantially re-.za the formation of insoluble homopolymer by-products and produce products having improved and/or modified properties is disclosed in US-A-3,418,354.
  • the method disclosed therein generally involves preparing a mixture of an olefin and a catalytic amount of a peroxide containing a peroxide group linked to a tertiary carbon atom and slowly adding said mixture to a poly(oxyalkylene) compound which is maintained at a temperature high enough to cause the grafting reaction to occur.

  • graft copolymers of poly(oxyalkylene) com - pounds disclosed are known to significantly enhance the retentivity thereof to substrates such as textile materials and none of the materials disclosed form graft copolymers which are crosslinkable.
  • graft copolymers consist of polyoxyalkylenes onto which, among various others, N-methylol derivatives of acrylamide are grafted.
  • the polyoxyalkylenes are prepared by copolymerizing a mixture of epoxide compounds, one of which must contain a free carbon-carbon double bond, thus resulting in polyoxyalkylenes containing unsaturated moieties in their branch portions.

  • a catalyst is employed in the process of the invention which is a free radical initiator (grafting catalyst).
  • grafting catalyst a free radical initiator
  • the choice of such initiator is important but any one of a wide variety of known inorganic or organic free radical initiators may be used.
  • the choice of initiator will generally depend on the particular combination of reactants from which the graft copolymer will be prepared.
  • Suitable initiators are azobisisobutyronitrile; hydroperoxides such as t-butyl hydroperoxide and cumene hydroperoxide; acyl peroxides such as benzoxyl peroxide; peroxides such as t-butyl peroxypivalate, di-t-butyl peroxide, and t-butyl perbenzoate; peroxycarbonates such as diethyl peroxydicarbonate and diisopropyl peroxycarbonate; and persulfates such as potassium and sodium persulfates.
  • Homogeneous graft copolymers of the present invention which are substantially free (contains less than 2 percent by weight) of insoluble homopolymerized acrylamide derivative may be prepared by methods known in the art but preferably are prepared in accordance with the present invention by charging the reactants in two separate feed streams, advantageously in gradual and/or incremental amounts, one of which consists of the grafting monomer and a second consisting of the free radical grafting initiator. Either of the reactants may be mixed with a portion of the poly(oxyalkylene) compound prior to feeding them to the reaction zone which when doing so facilitates the gradual or incremental feeding thereof to the reaction mixture.
  • the amount of acrylamide derivative added to the polymerization reactor zone is not critical and may be varied over a wide range. In general, however, up to 70 percent by weight, and preferably from 1 percent by weight to 50 percent by weight based on the total weight of the final graft copolymer, is charged.
  • the temperatures at which the graft reaction of the present invention may be carried out may vary over a wide range and depend, in general, upon the combination of reactants to be used in the reaction.

  • a temperature from about above the freezing point of the solvent to about 65°C may be employed. Reaction temperatures above 160°C lead to gelling of the reaction mixture, and should be avoided.
  • Incremental and/or gradual addition of the two separate reactant feed streams coupled with efficient agitation of the poly(oxyalkylene) compound in the reaction zone constitutes the most important technique for producing the graft copolymers of the present invention.
  • This method is particularly important in large scale or commercial operations, not only for preparing the desired homogeneous graft copolymer, but also to facilitate handling and storage of the monomer and the free radical initiator.
  • the grafting reaction of the invention is preferably carried out in bulk without the use of a solvent.
  • a solvent may be used which is non-reactive and inert to the reactants.
  • Suitable solvents include benzene, toluene, tertiary-butylbenzene, heptane, hexane, or octane, and mixtures thereof, and water.
  • the graft copolymers of this invention provide poly(oxyalkylene) copolymers which are crosslinkable, thus rendering them significantly more retentive to a wide range of substrates including textile fibers and fabrics. Moreover, such graft copolymers have been found to have modified and improved properties which render them more useful than the base poly(oxyalkylene) polymers as lubricants for materials such as metals, textiles, fibers and carpets.
  • graft copolymers of the invention crosslink on exposure to heating at, for example, 100-150°C
  • organic catalysts such as para-toluenesulfonic acid, citric acid, and the like are generally added to accelerate crosslinking.
